CARPET-CLEANING APPARATUS. I I r SPECI'FIGATION forming part' of'Letters Patent No. 271,406, dated January 3o, 1853.

Application ined May 23,1882. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM BOWMAN and ERNEST HUNSCHER, both ofCleveland, in the county of Cuyahoga and State of Ohio, have invented anew and Improved Apparatus tor Cleaning Carpets, ot which the followingis a full, clear, and exact description.

This invention relates to improvements in thatclass ofcarpet-cleaners,in which the cleaning is done by the tumbling andrubbing process; and it consists in the combination and arrangement ofparts, substantially as hereinalter more fully set forth.

We constructa tower ot' suitable height and provide an endless ycarrierfor elevating the carpets, and also friction or tumbling trames, overwhich the carpets roll in their descent, as hereinafter described andclaimed.

Reference is to be had to the accompanying drawing, in which ourcarpet-cleaning apparatus is shown by a perspective elevation.

A A is the framework of the tower, which is to be of any suitableheight. At the lower part of the tower are cross-shafts a a, titted insuitable bearings and provided with pulleys b, and Vat the upper partot' the tower are similar shafts and pulleys a b.

Around the pulleys b b is fitted an endless apron, B, composed ot' beltsc, to which slats d are attached.

Within the frame-work ofthe tower are the breakers or friction-frames D,which are placed at suitable distances apart and inclined in oppositedirections alternately. These frames D are provided with rollers e andslats to form a surface over which the carpets roll, and the frames arepivoted at one end and connected at their outer ends to a center bar,f,by a screw and nut, as shown at g, so that their inclination may bevaried, the object being to regulate the speed at which the carpets moveover the frames, less inclination being required with heavy carpets thanwith lighter ones.

The endless apron is provided at intervals with shelves, pockets, orcarriers h, which are attached to the inner side ot' the apron forelevating the rolls of carpet.

In operation, power is to be applied to one ot' the shafts a to give amovement to the endless apron. The rolls of carpeting are placed uponthe apron between the lower pulleys, and are carried upward by theshelves h until they reach the upper end of the tower, when they rollover upon the frame D, and are passed from thence to the next frame, andso on downward until they reach the bottom. By this movement the carpetsare turned end tor end and rolled and tumbled about so that,practically, they clean themselves and no one carpet comes in contactwith another.

The operation being in the open air, and the tower open at all sides thedust and dirt are carried away. By making the tower of suitable heightand strength and giving to the belt the necessary speed the apparatuscan be made to do the work rapid-ly, and the cleaning will beei'ectively done at a much less expense than by the ordinary beating'operation. p

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. `The carpet-cleaning apparatus consistingot' the tower A, the endless apron B, provided with carriers h, and theseries ot inclined friction-frames or breakers D, substantially asdescribed,combined for operation as set forth.

2. In carpet-cleaningapparatus, the adjustable frames D, provided withrollers c, in combination with the elevating belt or apron B,substantially as shown and described.
